Hydrogen as energy carrier for fuel battery has been the development of new energy vehicles. Recently, however, Automotive Engineering, Tsinghua University and Development Research Institute, Mr. Song Jian, Vice-President stressed that the high cost of vehicle fuel Laptop battery, hydrogen is difficult, the technology of fuel batteries for development of new energy vehicles does not seem practical.

The high cost of vehicles to hydrogen fuel battery is difficult

Vehicle fuel battery operating principle is: always sent by the fuel battery hydrogen fuel and oxygen under the influence of the catalyst in water while producing electricity driven generator to drive the wheels turning. Although this new energy vehicles emit virtually zero, but due Song, costs are high, restricting future development of hydrogen is difficult. "Fuel Dell Inspiron 5150 batteryin the car can not replace anything, just a device for converting energy, is equivalent to the rising cost of cars." Song said: "The current generation technology of fuel batteries, the price per kilowatt-General to $ 20,000 U.S. Even in 2035 before the older generation, but also the price per kilowatt of about 20,000 yuan. "Total cost of more expensive vehicles, one year for use during the Olympics, no large-scale production of fuel battery version of the Passat, for example, the cost may be nearly one million yuan each.”Vehicle fuel battery is still in the ‘Run Model’ State, at home and abroad is not mass production. "Said Song.

In addition to manufacturing costs are high, the hydrogen is also difficult for low-cost access to one of the problems encountered. Song said: "At this hydrogen by electrolysis of water: the acquisition, use a high cost. Because it is gas, there is a huge and difficult, it is difficult to store and transport. And even in the small spark of static electricity can easily ignite under, there are a security risk. "optimal use:

The most appropriate storage of solar wind

The technology of fuel VGP-BPS2B batteries for the development of new energy vehicles does not seem practical. But Song made, using similar techniques to construct the station energy storage power, stabilize the voltage, frequency, regulate peak electricity and the valley, but it added a good choice. "Wind energy, solar energy by the excellent weather conditions and volatile output, if they are directly integrated into the grid, would damage the quality of food." He explained, "it would better as a fuel conversion device batteries, wind energy, energy issues Solar Electric in situ electrolysis of water into hydrogen and oxygen, then through the fuel battery to generate the electricity. it would lead to the voltage stability of power, frequency stability, and better suited to enter the gate. when hydrogen becomes a storage medium for energy. "

Song also said that, initially designed for generators to power fuel hp PB992A battery car, has the characteristics of fast start, can not simply be used to adjust peak and valley. Consumption in the trough, to ensure energy efficiency, excess capacity may be the first store. Wait until rush hour, just 12 seconds of time, fuel batteries can bring electricity to be released.

However, given the current high cost of fuel batteries and abroad have not used it as an attempt of energy storage power plants.
